why would “cognitive faculties” that help us survive necessarily be in conflict with producing true beliefs?
After all, a tendency to produce true beliefs as opposed to being delusional is surely almost always (if not simply always) GOOD for survival!
The rest of your post doesn't make any sense.
Say an animal needs to escape from a preditor. Ie. a monkey needs to avoid being eaten by a lion.
It needs the proper belief / reaction pair to set its body in motion to avoid being eaten. Now the argument is that as long as the belief / action gets the monkey's body away from the preditor, it will survive. The reason for its removal may be based on a right belief or a wrong belief. Evolution couldn't give a flip as long as the body of the monkey is removed from the monkey eater.
Now here are some belief pairs that might yield effect for monkey survival:
1.) The monkey is afraid that the preditor is going to harm it. So it gets away.
2.) The monkey thinks the preditor and the monkey are in a race, so the monkey takes off to win the race.
3.) The monkey regards the preditor as a playmate, perhaps like a big furry cat. And the monkey runs to get the preditor to chase it and play some more.
Evolution couldn't care less if the monkey's belief is factual or not. As long as the proper response of getting the monkey's body out of there, evolution doesn't care.
The argument is something like that. What Evolution needs is simply the right move of the organism. Whether that move has as its bases a belief that is true or a belief that is false doesn't matter.
The argument is something like that. Naturalism and Evolution as a pair logically lead to realization that our cognitive falculties cannot be trusted to realize what is true. They can only be useful to yield the benefitial response of the organizim which leads to its survival.
What we regard as truth then about man is not reliable. Only what has yielded the appropriate benefitial survival reaction can be trusted.
